My chicks are in their coop (which, because they are my first chickens, is also my brooder! Fancy that.) Weather is in the 90s in the day and the 70s at night. The chicks are 8 days old and snuggle under the heating pad at sundown. How long until I can unscrew the door to the (predator proof) run? I don’t want them to get mixed up and not go in for food and water or supplemental heating under the MAma heating Pad while I am at work. There is a tarp over 80 percent of the run so it is almost fully shaded during the day. Shortly after the same time as the chicks are ready for this step I want to put the waterer outside of the coop also. I know on Saturday at 6 days old they had no interest in jumping onto that ramp so that could be a ways away yet.
